RubberMaster S368

FEATURES AND BENEFITS

  • Enhanced controllability
  • Increased load durability
  • All season traction

OVERVIEW

The RubberMaster S368 is a highway terrain, all season tire made for trailers. This tire is NOT MEANT TO BE MOUNTED ON LIGHT TRUCKS, as its construction will not support the weight and performing style of such vehicles. It can ONLY BE MOUNTED ON TRAILERS.

Great performance and handling are promoted with this tire. The flat ribbed footprint closely follows the road throughout the drive. This effectively improves its steering responsiveness and towing stability. It results in quick and precise steering responses, as well as a secured structure. Cornering is upgraded with shoulder ribs that provide additional biting edges.

The tire is able to handle versatile weather conditions. Better dry, wet, and light winter grip is offered with the detailed tread design and the all season compound. Stronger rubber materials keep the tire pliable throughout the year, optimizing its summer and winter performance. Additionally, the tread’s sipes create biting edges, upgrading its road grip. Grooves combat hydroplaning in wet conditions. They channel water and slush from the footprint, increasing its wet grip.

The RubberMaster S368 improves its load and driving durability. This tire features a robust structure that does not deform under load and driving pressure. As the tire does not deform, it is able to securely carry and withstand heavy loads. This optimizes the tire’s overall load durability, optimizing its heavy-duty applications.

This specific tire model features a BIASED ply construction.

Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
